LEDLM-84PL LED Lumen Maintenance and Aging Life Test System is designed according to IES LM-84 and TM-28. It is used to test & record the optical and electrical maintenance for LED luminaires. The software is based on Arrhenius model and TM-28 to calculate the LED life. The LEDLM-84PL needs to work with GDJW Series High and Low Temperature Chamber (Option is GW Series) and LSP-1KVARC AC Power Source. Please click to view the test report samples of LM-84 and TM-28.

LEDLM-80PL LED Lumen Maintenance and Aging Life Test System is designed according to IES-LM-80 and TM-21. It is used to test & record the optical and electrical maintenance for single LEDs or LED module. The software is based on Arrhenius model and TM-21 to calculate the LED life. The LEDLM-80PL needs to work with GDJW Series High and Low Temperature Chamber (Option is GW Series) and and DC6010 Series DC Power Source. Please click to view the test report samples of LM-80 and TM-21.

LED has the feature of long life, but its life will be different with the different working condition and driver current. Generally the life will be around 50K hours. Different from the traditional lightsource, LED light will decay gradually rather than extinguish instantly.
1) L70 (hour): time to 70% lumen maintenance
2) L50 (hour): time to 50% lumen maintenance

Standard:
IES LM-84 “Measuring Optical Radiation Maintenance of LED Lamps, Light Engines, and Luminaires”
IES-LM-80 ” LED Lumen Maintenance and Aging Life Test “
LM-79-19 “Optical and Electrical Measurements of Solid State Lighting Products”

Specification:
• Record the changing curves of lumen, colorimetric and electrical parameters VS time
• Test and record the light attenuation data within a short time, then software will predict the LED life
• Introduction to Arrhenius Model, make the final result more reliable and efficient
• The LEDLM-84PL test system works with LISUN GDJW-015A GDJW Series High and Low Temperature Chamber can test 8 LED luminaires at one time; the LEDLM-80PL test system works with LISUN GDJW-500A  High and Low Temperature Chamber can test 16 single LEDs or LED module at one time . (Option 1: Up to 3 sets Temperature Test Chambers can be connected to work with LEDLM-84PL/LEDLM-80PL at the same time for testing. Option 2: Other size High and Low Temperature Chamber)
